Description

DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD The present invention relates to an antiperspirant composition and a deodorant composition comprising cyclohexasiloxane as a volatile silicone carrier for improving product stability, performance and / or cosmetics. .

BACKGROUND OF THE INVENTION There are a wide variety of topical antiperspirant and deodorant products that are commercially available or otherwise known in the antiperspirant and deodorant industry. Most of these products are formulated as aerosol or pump sprays, spin-on solutions, creams, emulsions, gels, gel solids, or other solid or semi-solid sticks, and are sold in suitable carriers Contains incorporated deodorants (eg, triclosan) and / or astringents (eg, zirconium and / or aluminum salts).
These products are designed to effectively control perspiration and / or odor during and after application to the axilla area or other areas of the skin and to be cosmetically acceptable.

[0003] Within this family of products, antiperspirant deodorant products containing volatile silicone fluids have become particularly popular among consumers. These products can be aqueous or anhydrous and can contain up to about 90% by weight of a volatile silicone fluid, ie, most commonly cyclotetrasiloxane and / or cyclopentasiloxane. The volatile silicone gives the composition a dry skin feel during application and evaporates quickly after application due to its volatility, leaving a smooth and dry feel on the application surface and originating from the volatile silicone material No white mark remains.

[0004] However, there are a number of limitations regarding the use of these volatile silicone materials in antiperspirants. These substances evaporate quickly from the skin after application, leaving residues of other solid substances such as antiperspirant actives and suspending agents on the skin. Because of this residue problem, these volatile silicones are commonly used in combination with residue masking substances, such as liquid dimethicone and other non-volatile silicones and organic emollients. Volatile silicones containing clear emulsions of antiperspirants have been found to be less stable, resulting in the clear emulsion becoming white over time.

[0005] At present, antiperspirant and deodorant compositions containing volatile silicones offer low persistence and / or product stability by selecting cyclohexasiloxane as the volatile silicone material. It is recognized that it can be improved. These selected volatile silicones reduce the visible residue of the antiperspirant composition after topical application and, when formulated in a clear emulsion, reduce whitening and turbidity that occurs over time in the formulated emulsion. Improves product stability.

Accordingly, it is an object of the present invention to provide a low-residue antiperspirant and deodorant composition containing cyclohexasiloxane as a selected volatile silicone material, and furthermore, cyclohexasiloxane. It is to provide a transparent antiperspirant emulsion containing siloxane and having improved stability. And it is a further object of the present invention to provide a clear antiperspirant emulsion containing other volatile silicone substances, which maintains the clarity of the product over a long period of time, as compared to similar other compositions. That is.

SUMMARY OF THE INVENTION Disclosed herein are antiperspirant and deodorant compositions with improved product stability and / or low persistence. These compositions contain a selected concentration of cyclohexasiloxane, an antiperspirant active, and a suspending agent, wherein the composition is preferably substantially free of cyclotetrasiloxane.

[0008] The choice of cyclohexasiloxane over other volatile silicone materials such as cyclotetrasiloxane and cyclopentasiloxane improves low persistence, especially when formulated as an aqueous emulsion, and the emulsion becomes transparent or translucent. It has been recognized to improve product stability in the form of extended periods of stay.
